Migrating from legacy ASP.NET to .NET 8 can seem challenging, but it can be simplified with a structured approach:

1. Assessment: Analyze your existing application’s structure, dependencies, and external integrations.
2. Preparation: Upgrade legacy libraries and NuGet packages to compatible versions first.
3. Code Migration: Gradually migrate WebForms or MVC pages to Razor Pages or Blazor.
4. Refactoring: Improve your application structure during migration (consider Clean Architecture).
5. Testing: Continuously test each migration phase to catch issues early.
6. Deployment: Use incremental deployment to production with thorough monitoring.

Migrating incrementally minimizes risk and maintains continuous delivery of business value.
